***Note:This engine harnesses uses OBD1 (92-95) ECU Connectors*** MADE IN THE U.S.A.This harness uses Mil-Spec Teflon coated wire with a maximum heat rating of 200°C.Our D-series and B-series compatible wire-tuck engine harness is nearly identical to our Mil-spec engine harness line with the primary difference being, the single black wire color and expandable loom.There are quite a few options available. Please look through them carefully to make sure you get the right parts!Vehicle Type: Select your vehicles chassis type.This tells us what interior "Chassis Adapter" to use for your setup.Injector Adapters: The Injector adapters dropdown menu has all the adapters you would need if you're selecting the OBD1 or OBD2 connectors but require a different Injector type only. (Look at this list if you don't know which type you have.)Alternator Adapter: We currently only have OBD0/1 to OBD2 adapters (Not 2->1), so if you have an OBD1 alternator: You will want to order the OBD1 Version of this harness and be sure to select the adapters for the OBD2 injectors and distributor if necessary.This can be confusing, feel free to call us.OBD2a ECU: This option will add the OBD1 to OBD2a ECU adapter for an additional $90.Charge Harness:• The "non-separated charge harness" option will add the Starter & Alternator leads to the fuse box. If you are not running your own Alternator power lead, you should add this. (+$30)• If you are relocating your battery, with our Starter Fuse box lead, all you need to do is run a heavy gauge wire to the starter from your 12v+ battery terminal in order to get 12v+ power to your fuse box. All connectors and materials are new. Each connector is crimped with pneumatic heads to ensure an OEM crimp every time, then tagged with a white identification label for easy installation. All heavy interference circuits are protected and grounded with proper wire covering. Our engine harnesses are 100% quality tested pin to pin; And resistance checked to ensure no voltage fluctuations.All Rywire engine harnesses are made with OBD1 (92-95) ECU Connectors.An ECU adapter must be used for OBD2a or OBD2b ECU's if necessary.Our harness does not support USDM OBD2 ECU's.Aftermarket ECU's using OBD2 plugs & Non-US OBD2 ECUs are compatible! (except for H22 and GSR stock computers).Each harness will come with a custom back side sub-harness that will be proprietary to the chassis you choose on the drop down menu. This way if you ever change chassis you will only need a new sub-harness, not a whole new wire loom!These harnesses are warrantied and guaranteed to work, however they are non-refundable. Because the back-side (interior/shock tower connection) separates from the main harness, the engine harness can be used on multiple chassis provided the engine itself uses the same components. We sell the back-side harness separately only over the phone for previous engine harness customers.
